To be honest, assuming you are using a desktop, the rules for ufw are sufficient (if not overkill). The rules are reviewed by the Ubuntu Security team.

sudo ufw enable

If you want a graphical front end, use gufw

sudo apt-get install gufw

Then search your menu for firewall.

Other then that , there is no single set of fool proof rules that applies for all users all the time. If the above command is insufficient we would need to know why they are insufficient in order to give better advice.
